Subject: [PATCH v3 0/4] drm: Provide a simple encoder
Date: Tue, 25 Feb 2020 14:10:51 +0100 [thread overview]
Message-ID: <20200225131055.27550-1-tzimmermann@suse.de> (raw)
Many DRM drivers implement an encoder with an empty implementation. This
patchset adds drm_simple_encoder_init(), which can be used by drivers
instead. Except for the destroy callback, the simple encoder's implementation
is empty.
The patchset also converts 4 encoder instances to use the simple-encoder
helpers. But there are at least 11 other drivers which can use the helper
and I think I did not examine all drivers yet.
The patchset was smoke-tested on mgag200 by running the fbdev console
and Gnome on X11.
v3:
* remove drm_simple_encoder_create() for lack of users (Sam, Daniel)
* provide more precise documentation (Sam)
v2:
* move simple encoder to KMS helpers (Daniel)
* remove name argument; simplifies implementation (Gerd)
* don't allocate with devm_ interfaces; unsafe with DRM (Noralf)
Thomas Zimmermann (4):
drm/simple-kms: Add drm_simple_encoder_{init,create}()
drm/ast: Use simple encoder
drm/mgag200: Use simple encoder
drm/qxl: Use simple encoder
